Understanding the Production Challenge<br />
Plunger Lift technology is a cost effective and efficient technique to deliquify and optimize oil and gas production in<br />
wells which have nominal flow trends. By optimizing production and reducing operating costs, each well becomes<br />
more profitable. When wells first begin producing, gas and fluids flow to the surface naturally. However, consistent,<br />
natural flow usually won’t last long. Liquid begins to collect against the walls of the tubing and starts to fall back<br />
accumulating at the bottom of the well. Liquid fall back continues and slugs of fluid are produced. As fluid slugs travel<br />
to the surface, as much as 75% of the fluid may fall back and continue to accumulate downhole. This accumulation<br />
of fluid is known as “liquid loading” and can be detrimental to well production. Without assistance, the column of<br />
fluid will grow too heavy for gas to pass through…and the well stops producing.<br />
Delivering the Right Solution<br />
A Plunger Lift System is an ideal solution for these well conditions. The plunger system uses an interface seal<br />
between the accumulated fluid and the stored gas in the annulus. The well is shut-in to allow the plunger to travel to<br />
the bottom which creates a bottomhole seal and well pressure to build. After a period of shut-in time, the head gas<br />
is blown down creating differential pressure across the plunger which brings the plunger to surface. As the plunger<br />
travels up the tubing, it lifts the fluid column to surface and a turbulent seal is formed which practically eliminates<br />
liquid fall back. The fluid column is lifted up and out allowing the well to produce again.<br />
The NOV Monoflo plunger lift system is the most economical and environmentally friendly form of artificial lift<br />
technology on the market today. The system is comprised of a well specific plunger, a bottom hole bumper spring,<br />
a specialized lubricator and catcher assembly, our electronic ControlOp controller, a motor valve and an arrival<br />
sensor. With the advanced controls and wide variety of optimization solutions, NOV Monoflo is able to offer a cost<br />
effective and environmentally friendly solution.<br />

Plungers<br />
Our plungers are available in a variety of models and sizes, manufactured with the objective of improving production<br />
rates and operating in various well conditions. Contact us for information on sizes and availability.<br />
Pad Plungers<br />
Our pad plungers utilize a unique pad design to provide<br />
superior seal efficiency and rugged durability for clean<br />
well bore fluid conditions. Available in either a single or<br />
dual pad configuration.<br />
• The raised shoulder design on the fish neck gives<br />
additional durability and energy displacement<br />
• Interlocking pad design provides superior gas and fluid<br />
seal<br />
• Built rugged utilizing a dual support rail design<br />
• Stainless steel design applicable for both sweet and<br />
sour applications<br />
Bypass Plungers<br />
The bypass plunger is designed for faster fall time by<br />
allowing fluid to flow through the plunger rather than<br />
around it. Designed to be deployed while the well is<br />
producing.<br />
• The mechanical seal allows more gas bypass which<br />
results in a faster fall and less downtime<br />
• Removable plugs allow for customized fall rates<br />
• Contoured rings allow for a superior turbulent seal<br />
• The bypass functionality allows the plunger to fall<br />
against the production flow<br />
• Available in 4140 alloy steel for sweet service or stainless<br />
steel for sour service.<br />
Bar Stock Plungers<br />
Our bar stock plungers are low maintenance and ideal<br />
for wells that require paraffin and scale control.<br />
• The raised shoulder design on the fish neck gives<br />
additional durability and energy displacement<br />
• Built in wear grooves for easy service<br />
• Can be easily modified for a variety of tubing<br />
conditions<br />
• The rifled top and bottom create a helical rotation that<br />
produces a superior turbulent seal (Rifled Plunger Only)<br />
• Available in 4140 alloy steel for sweet service or stainless<br />
steel for sour service.<br />
Brush Plungers<br />
Our brush plungers are designed for maximum sealing<br />
efficiency sandy conditions.<br />
• The raised shoulder design on the fish neck gives<br />
additional durability and energy displacement<br />
• Excellent sealing efficiency<br />
• Ideal for use in wells that require sand removal both<br />
produced and Frac<br />
• Durable 6.6 Nylon Brush design for harsh conditions<br />
• Designed with a replaceable brush for superior<br />
economics<br />
• Available in 4140 alloy steel for sweet service or stainless<br />
steel for sour service.
Bottom Hole Bumper Springs<br />
NOV Monoflo bottomhole bumper spring<br />
assemblies are designed to absorb the impact of<br />
the plunger when it reaches the bottom of the well.<br />
Various seating assemblies can be used (e.g.: hold<br />
down, seal stop, tubing stop, collar stop) depending<br />
on the application. We offer bumper springs in<br />
various sizes and materials suitable for use in sweet<br />
and sour service environments. All of our bumper<br />
springs are designed for maximum flow area without<br />
compromising strength. A ball and seat can also be<br />
used to retain liquids in the tubing string.<br />
• Easy to set and retrieve<br />
• Large flow area<br />
• The raised shoulder design on the fish<br />
neck gives additional durability and energy<br />
displacement<br />
• Stainless steel material<br />
• Spring material available in Inconel X750, and<br />
MP35<br />
Lubricators<br />
NOV Monoflo lubricators are spring-loaded receivers<br />
designed to cushion the arrival of the plunger at<br />
the surface. The lubricator has a catcher designed<br />
to catch the plunger upon arrival which allows the<br />
operator to retrieve and inspect it. Available in a<br />
variety of sizes and in special materials built rugged<br />
for the harshest environments.<br />
• Built to API 6A specifications<br />
• Field serviceable<br />
• Suitable for high pressure applications<br />
• Sweet and Sour service available<br />
• Cold temperature material good to -50°C<br />
• Threaded and Flanged available<br />
• Single and Dual Port available<br />
• Threaded and Bowen Union available<br />
• Extensive testing, pressure, hydro, and X-ray<br />
